40 000 N, what is the area of each foot?​

Answer 1

Answer:

.........,...............@..........%

Answer 2

Answer:

Area of each foot is 0.4 m²

Explanation:

If Standing On 4 feets :-

Pressure = 250,000 Pa

Force = 40,000 N

Surface Area = ?

$pressure = \frac{force}{surface \: area} \\ = )250000 = \frac{40000}{surface \: area} \\ = )surface \: area = \frac{40000}{250000} \\ = )surface \: area \: = 0.16 {m}^{2}$

NOW :-

$surface \: area \: of \: 4 \: feet \: = 0.16 \\ = )surface \: area \: of \: 1 \: feet \\ = ) \frac{0.16}{4} \\ = )0.4 {m}^{2}$
